The Hull Side Reinforcement Plate is attached to the hull with (2) AN4 Bolts and 3/16" rivets to the side of the hull. This new option will strengthen the hull in the area just aft of the seats. Repairs to a hull in this area cannot be preformed without removal of the hull from the airframe.
If your hull is showing stress cracks, this is the best option to strengthen the side of the hull preventing further cracks from developing. Two are required per airframe. Powder Coating available as an option.
The Hull Side Reinforcement Plates are standard on the certified Searey, and optional on the LSX Kits.
